MGV servomotors are cooled by water. An anti-corrosion product must be mixed to the water. The main
characteristics of cooling are given in the table bellow:
Motor cooling circuit data and chiller selection
Chiller must be able to evacuate motor power loss (see table above).
Chiller pump must provide water flow through motor and pipe pressure drop.
Inlet temperature must be inferior to 25°C.
You can find various chillers solutions in Parker Hiross -
